The invention discloses a gas inlet mixing device. The gas inlet mixing device comprises an EGR gas inlet pipe, a gas inlet pressure stabilizing cavity and an EGR distribution pipe located in the gasinlet pressure stabilizing cavity, wherein the gas inlet pressure stabilizing cavity is provided with a fresh gas inlet connector and an EGR gas inlet connector, the EGR gas inlet pipe communicates with the EGR distribution pipe through the EGR gas inlet connector, and a plurality of gas outlet holes corresponding to gas inlets of air cylinders are formed in the EGR distribution pipe in the lengthdirection. Due to the pressure stabilizing effect of the EGR distribution pipe, the influence of EGR gas inlet pulses on gas mixing is reduced, the mixing effect of EGR gas and fresh inlet gas is optimized, and therefore the gas inlet mixing device is good in universality under various working conditions. The invention further discloses an engine comprising the gas inlet mixing device. 本发明公开了一种进气混合装置，包括EGR进气管、进气稳压腔和位于所述进气
